Nah, a #2 type pencil eraser does the job, fine.

Yah,an eraser will also remove plating (used on many) and won't afford
any corrosion protection.

Plating? On the charging contacts? Never had that problem on any
of the phones I have had. *What* plated over *what* ??

I don't know the details here, but there is lots of plating out there,
even on very cheap stuff. I noticed when some batteries leaked.

We're talking about the contacts on the *outside* of the phone and on
the charging base, not the internal battery contacts. And don't most
cordless phones use plugs and pins instead of the ordinary battery
contacts?
